How to do it...

In this section, we are filling an std::vector instance with some example integers, and then prune some specific items away from it. The way we are doing it is considered the correct way of removing multiple items from a vector.

1. Of course we need to include some headers before we do anything.

      #include <iostream>      #include <vector>      #include <algorithm>

2. Then we declare that we are using namespace std to spare us some typing.

      using namespace std;

3. Now we create us a vector of integers and fill it with some example items.

      int main()      {          vector<int> v {1, 2, 3, 2, 5, 2, 6, 2, 4, 8};

4. The next step is to remove the items. What do we remove? There are multiple 2 values. Let's remove them.

 const auto new_end (remove(begin(v), ...
